“…The reasons behind this lack of deep ultraviolet microscopes are probably due: first, to the fact that traditional glass lenses cannot be used, because of their strong absorption of ultraviolet light [3]. Second, bright enough deep ultraviolet sources were very few, hard to operate and maintain safely, and in addition they require high power to operate.…”

This article presents the design, construction, and results obtained by our new compact, small and inexpensive deep UV microscope. Several methods are described for recording microscopic images of various types in the deep ultraviolet spectral regime (200 nm -300 nm). The techniques employed utilize CCD cameras, de-bayered webcam sensors, photographic paper and cyanotype coated paper as detectors.In addition, we describe the techniques employed and results obtained by utilizing a cellphone camera to record deep ultraviolet microscopic images. The instrumentation techniques, presented in this paper are expected to be most useful in areas where compact, handheld systems, are needed for in field applications.

“…11 The aim of this current work is to prove that this method is reliable and does not compromise the quality of the samples based on the new GLS-Se compositions. Past work on the drawing of some chalcogenide-based glasses has benefited indirectly from residual oxides in the glass 12 or by intentional doping with oxides, as in gallium lanthanum sulphide oxide compositions 13 where the oxygen content acts as a thermal stabilizer. 14 With GLS-Se compositions, however, oxides compromise the infrared (IR) transmission thus the challenge faced here is to produce rods and structured preforms, which are oxygen free.…”

Chalcogenide glasses are amorphous solid materials formed from chalcogen elements bonding with metals to form typically in binary or tertiary compounds. One family of chalcogenide glasses, based on gallium and lanthanum sulphides, possesses properties important for the infrared (IR) window transmissions and IR applications; these include thermal stability, high solubility of rare earth ions, low phonon energy and high laser damage threshold. Efforts have been made to produce new chalcogenide glasses that can extend the IR transmission window further into the IR. Work has led to the successful melting of a selenium-modified gallium lanthanum sulphide (GLS-Se) glass that can transmit up to 15 μm, however these glasses have, to date, only been demonstrated in bulk glass form. We aim to develop processes for the fabrication of chalcogenide optical fiber to exploit the properties of chalcogenide glasses. Several potential applications include sensing for the civil, medical, and military areas, as these materials offer transmission over much of the molecular fingerprint region (2 to 25 μm). The aim of our work is to understand and control the thermal properties and stability of GLS-Se glasses without compromising their optical properties, in order to produce transparent glass rods and demonstrate the feasibility in fabrication for structured optical preforms by extrusion, as the first step to achieve optical fiber from GLS-Se glass.

“…[8][9][10][11] Several types of nonsilica glasses with highly nonlinear optical responses have been used recently to develop optical fibers. [12][13][14][15] Lee et al achieved DFWM over a 10 nm bandwidth in a bismuth oxide fiber. 16) 19) In a tellurite fiber, DFWM wavelength conversion with an efficiency of −20 dB has been demonstrated in a step-index fiber with the ZDW located around 1908 nm.…”

Wavelength-tunable picosecond degenerate four-wave mixing was demonstrated in a tellurite microstructured optical fiber (TMOF). The zerodispersion wavelength of the TMOF was shifted to 1570 nm by introducing a single ring of air holes in the cladding. The anti-Stokes signal sideband can be generated from 1490 to 1500 nm, and the Stokes idler sideband can emit from 1595 to 1645 nm. Because of the high nonlinearity of the TMOF and the large peak power of the picosecond pump, a maximal signal gain of 31.2 dB and an idler conversion efficiency of +35 dB were achieved.
